2015-03-25 13:31:28 -0500	commented answer	Failed to parse owl-file with migrated Knowrob package With (OR) it works! And I had some missing dependencies, so now the query works too! Thanks so much!
2015-03-25 12:07:34 -0500	commented answer	Failed to parse owl-file with migrated Knowrob package I tried this `<param name="initial_goal" type="string" value="owl_parse(a),owl_parse(b)" />` and only the first owl file is parsed.
2015-03-25 11:26:10 -0500	commented answer	Failed to parse owl-file with migrated Knowrob package Is it possible to load multiple files from launch file?
2015-03-25 11:20:56 -0500	answered a question	Failed to parse owl-file with migrated Knowrob package HI @moritz, thanks for your answer. I tried replacing 'owl_parser:owl_parse' with just 'owl_parse' and I get exactly the same warnings. However, if I upload data from an owl file within the launch file using: as explained in the migrating tutorial, it works! But only for this initial owl file. If I try to upload more within the init.pl it gives the same error. Is there way I can upload more that one owl file from the launch file?

2015-03-24 10:21:19 -0500	asked a question	Failed to parse owl-file with migrated Knowrob package Hello KnowRob Developers, I'm trying to migrate a knowrob/rosbuild package to the catkinized/rosjava version following the very useful instructions here, everything seems to compile correctly, I am able to run a java exectuable which converts yaml files into owl files. The package can be found here. The package basically consists of starting the knowledge base with two owl files knowrob-seds.owl and dummy-task.owl. This used to work perfectly in the rosbuild version of the package, but now that I have migrated I get the following warnings, when starting the knowledge base and loaded the owl files: $ roslaunch rosjava_knowrob_seds knowrob_seds.launch % Parsed "knowrob-seds.owl" in 0.00 sec; 64 triples Warning: /home/nadiafigueroa/catkin_ws_knowrob/src/stacks/rosjava_knowrob_seds/prolog/init.pl:33: Goal (directive) failed: user:owl_parser:owl_parse(package://rosjava_knowrob_seds/owl/knowrob-seds.owl) % Parsed "dummy-task.owl" in 0.02 sec; 1,736 triples Warning: /home/nadiafigueroa/catkin_ws_knowrob/src/stacks/rosjava_knowrob_seds/prolog/init.pl:37: Goal (directive) failed: user:owl_parser:owl_parse(package://rosjava_knowrob_seds/owl/dummy-task.owl) % /home/nadiafigueroa/catkin_ws_knowrob/src/stacks/rosjava_knowrob_seds/prolog/init.pl compiled 0.03 sec, 4 clauses Warning: /home/nadiafigueroa/catkin_ws_knowrob/src/stacks/rosjava_knowrob_seds/prolog/init.pl:33: Goal (directive) failed: user:owl_parser:owl_parse(package://rosjava_knowrob_seds/owl/knowrob-seds.owl) Warning: /home/nadiafigueroa/catkin_ws_knowrob/src/stacks/rosjava_knowrob_seds/prolog/init.pl:37: Goal (directive) failed: user:owl_parser:owl_parse(package://rosjava_knowrob_seds/owl/dummy-task.owl) Which is curious to me, as to why it shows only as a warning, because when I try to query it from a python interface I get the following errors: $ rosrun rosjava_knowrob_seds test_seds_model.py Traceback (most recent call last): File "/home/nadiafigueroa/catkin_ws_knowrob/src/stacks/rosjava_knowrob_seds/rosjava_knowrob_seds/src/test_seds_model.py", line 23, in <module> query = prolog.query("""rdfs_subclass_of(Phase, seds:'SEDSMotion'), phase_properties(Phase, ID, Object, Threshold, Atractor, Models), member(Model, Models), motion_properties(Model, Type, GMMs), member(GMM, GMMs), gmm_properties(GMM, GMMType, InputType, InputDim, OutputType, OutputDim, Gaussians), member(Gaussian, Gaussians), gaussian_components(Gaussian, Mean, Cov, Prior), vector_elements(Mean, MeanVec),matrix_elements(Cov, CovMat)""") File "/home/nadiafigueroa/catkin_ws_knowrob/src/stacks/knowrob/json_prolog/src/json_prolog/json_prolog.py", line 69, in query return PrologQuery(query_str) File "/home/nadiafigueroa/catkin_ws_knowrob/src/stacks/knowrob/json_prolog/src/json_prolog/json_prolog.py", line 22, in __init__ raise PrologException('Prolog query failed: %s' % result.message) json_prolog.json_prolog.PrologException: "Prolog query failed: PrologException: error(existence_error(procedure, /(phase_properties, 6)), context(:(system, /('<meta-call>', 1)), _23))" and these on the knowledgebase side: jpl.PrologException: PrologException: error(existence_error(procedure, /(phase_properties, 6)), context(:(system, /('<meta-call>', 1)), _23)) at jpl.Query.get1(Query.java:336) at jpl.Query.hasMoreSolutions(Query.java:258) at jpl.Query.allSolutions(Query.java:556) at org.knowrob.json_prolog.query.AllSolutionsCommand.execute(AllSolutionsCommand.java:6) at org.knowrob.json_prolog.query.ThreadedQuery.run(ThreadedQuery.java:104) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) java.lang.Exception: jpl.PrologException: PrologException: error(existence_error ...
